(Cl. 2194-24)A s 1 claim.

My invention relates to devices for straightening kinky hair, and hasfor its primary object the provision of a scissors-like constructionwhich is manually operable and which' is adapted to be heated; theoperative portion thereof being provided with roller structure or rollermeans so as to effectively iron and straighten out a strand of l hairintroduced thereinbetween. f

Another object of my invention is to provide a device of theaforementioned character which may be electrically heated or to whichextraneous heat may be applied for ironing a strand of hair introducedbetween a pair of rollers adapted to contact one another tangentiallywhen closed in normal position. Y

Another object of my invention is to provide a device of theaforementioned character with rollers in which the manipulating handlesare secured in counter-sunk well means thus furnish# ing edges whichwill permit operation of the rollers freely on a strand of hair withoutendangering the accidental grabbing or catching of the said strand ofhair or portion thereof by the ends of the rollers.

Other objects, features, and advantages, inherent in my invention willbecome apparent from an examination of the accompanying drawing havingspecial reference to the ensuing description, wherein like numerals areutilized t designate like parts, and in which Fig. 1 represents aperspective view of one form of my invention.

Fig. 2 represents a plan view of that form of my invention exemplarilyindicated in Figure l, with certain portions thereof indicated incrosslsection so as to more clearly bring out the structuralrelationship of the elements involved.

Fig. 3 is a transversal cross-sectional view taken on the line 3-3 ofFigure 2.

Fig. 4 is a transversal cross-sectional view taken on the line 4-4 ofFigure 2.

Fig. 5 is a fragmentary plan view showing another form of my inventionwith certain portions thereof indicated in cross-section, the said formbeing a device which requires heating to be supplied from outsidesources.

Fig. 6 is an enlarged view of a modification of the form indicated inFigure 5 wherein the roller means is recessed at the extremities so asto conceal the attaching portion thereof, and to furnish a device whichwill be more eiiicient, will prevent the strand of hair from beingcaught handles I5 and v'scissors-like structure, generally, designated"I, is

comprised of two levers 8 and 9 being articulately fulcrumed or securedby virtue of the pivot screw or pin I0. The levers 8 and 9 are providedwith I 6 so as to accomodate' the thumb and one or more fingers of thehand vfor -manipulatingA the said instrument in a manner similar to theoperation of a scissors. structures 8 andl 9 are preferably formed for asubstantial distance thereof into substantially semi-cylindrical andhollow sections designated I"I and I2 for housing the electricalconnections to -be used with my invention.

The lever The said cylindrical sections II and I2 are shapedapproximately as indicated in the cross- Vsectional view Figure 2, andprovide a housing for'securing therein the electrical heating elements23 and 24, The rollers I4 and I3 are 'rotatably mounted and confinedbetween the co1- lars 30 which are secured to the portions II and I2 andthe washer elements29. 'I'he end of the sections I I and I2 are adaptedto receive the plug structures 28 which have reduced shoulders so as topermit the riveted portions 21 to be formed and confined in assembly tothe washer elements 29.

The lever 8 is y also provided with a tubing element 20 secured theretofor housing a terminal of the wire I1. The tube 20 serves as anadditional housing secured to the portion I2 for retaining theelectrical wire connection I'I which Y. to seeurethe y tween the washers35 and 34 a space sufiiciently therein, during the operation of ironingor terminates in a male plug I8 having the prongs I9 adapted to beinserted in an electrical wall receptacle or socket to furnish thenecessary electrical current for heating the heating elements 23 and 24.The said tubing 2U may be, preferably, secured to the handle portion ofthe lever I8 by means of the spring wire securing means 2| and 22. Thewire Il branches off to two double cord terminals 25 and 26 each beingconnected to heating elements 24 and 23.

In Figure 5, I show a form comprised of similar lever in whichthefterminals of rod portions der so as to of my invention structures 8and 9 the levers are reduced 3| and 32, having a reduced shoulpermitriveting the ends 33 thereto washers 34 and thus confining belarge toenable the rollers 36 to rotate freely therebetween.

In Figure 6, the reduced sections of the levers 8 and 9 are designated44 and are also provided with reduced shoulders to hold in fixedposition the Washer elements 41 and 46, the termini of the said leversbeing riveted over as indicated at 45 and thus confining the washers 4Gand 41 a suitable distance to provide freedom of rotation to the rollers49 which, as will be seen, have counter-bored recesses 43 and 42 inorder to provide smooth and obstruction-proof ends to the rotatingrollers thus preventing any of the hair iilaments from being caughtduring the operation, or rotation of the rollers when straightening thehair or ironing the same.

The strand of yhair to be straightened out ias placed in the openingconned between the rollers I4 and I3, or rollers 36, or rollers 40 and4l whenever it is desired to straighten kinky hair. 4

The rollers are then caused to be tangentially in contact with thestrand of hair placed therebetween, namely, at the contact lines 31, 38or 39, The arrangement indicated in Figure 1 being heated from asuitable source `of electrical supply will cause the hair to bestraightened by the application of heat and pressure simultaneously whenthe rollers Vare operated over the strand of hair which is held in onehand, its other point of anchorage being on the head of the personoperated upon.

In like manner, the devices of Figures 5 and 6 are utilized forstraightening out kinky hair and giving the same a permanent straightcharacter, with the exception that the structures of Figure 5 and Figure6 require heat to be supplied from a Bunsen burner, gas light, or othersimilar heating source of supply.

Altho, I have, herein, indicated preferred forms of my invention, it isunderstood that the same may be modified or amplified within the spiritand scope of the foregoing disclosure, as Well as the embodiments of theaccompanying drawings; my invention to be limited by the appended claim.

Having thus described and revealed my inventubular conduits merging intoone tion, what I claim as novel and desire to secure by Letters Patentis:

A device of the character described comprising, a scissors-like meansincluding a pair of crossed lever members, hollow cylindrical housingportions forrned on the termini of said lever members, a tubular conduithaving one oi its ends secured to the inner portion of one of saidcylindrical housing portions and configurative with the shape of thelever member tov which it is secured, its other end being secured to thehandie portion of the said lever member, wire clip means securing thesaid tubular conduit to the said handle portion, an auxiliary andcomparatively short tubular conduit secured to the inner portion of theother of said housing portions and terminating substantially at thepivotal point of the said lever members, a pair of heating elementsremovably secured within the confines of the said housing portions, apair of electrical conduits each secured to one of said heatingelements, the free ends of the said conduits beingtrained through thesaid housing portions, the said tubular and the said auxiliaryassemblage at the pivotal point ofthe said lever members, the free endof the said assemblage emanating through the terminus of the saidtubular conduit and having an electrical plug secured thereto, collarelements secured on the said housing portions, plug elements havingenlarged washer elements secured thereto driven into the open ends ofthe said housing portions, and roller means rotatably mounted on thesaid housing portions and confined against longitudinal displacementbetween the said collar elements and the said plug elements.
